You'll also need libcrmf.a on the system. That library is part of mozilla-nss package, but it got accidentally removed with all the other static libraries (which were intentionally removed). For the time being, you can (re)build mozilla-nss from the Slackware sources and grab the libcrmf.a library from it, put it on the system (in /usr/lib(64)), and go. Either Pat will do a rebuild for 14.0, or we'll host a libcrmf package on SBo.
